Its was difficult in past decades to communicate with your loved ones in just seconds but now its possible by cell phones. Short messages service (SMS) is a part of mobile and communication system. Now a days there are communications protocols that allows a person to communicate between mobile phones and landlines. SMS as used on modern handsets was originated from radio telegraphy in radio memo pagers using standardized phone protocols and later defined as part of the Global System for Mobile Communications (GSM) series of standards in 1985[2] as a means of sending messages of up to 160 characters,[3][4] to and from GSM mobile handsets.[5] Since then, support for the service has expanded to include other mobile technologies such as ANSI CDMA networks and Digital AMPS, as well as satellite and landline networks.[citation needed] Most SMS messages are mobile-to-mobile text messages though the standard supports other types of broadcast messaging as well. SMS text messaging is the most widely used data application in the world, with 2.4 billion active users, or 74% of all mobile phone subscribers. The term SMS is used as a synonym for all types of short text messaging as well as the user activity itself in many parts of the world. SMS is also being used as a form of direct marketing known as SMS marketing. Short messages may be used normally to provide premium rate services to subscribers of a telephone network. Mobile-terminated short messages can be used to deliver digital content such as news alerts, financial information, logos and ring tones. The first premium-rate media content delivered via the SMS system was the world's first paid downloadable ringing tones, as commercially launched by Saunalahti (later Jippii Group, now part of Elisa Group) in 1998. Initially only Nokia branded phones could handle them. By 2002 the ringtone business globally had exceeded one billion US dollars of service revenues, and nearly 5 billion dollars by 2008[citation needed]. Today, they are also used to pay smaller payments online, for example for file sharing services, in mobile application stores or VIP section entrance. Outside the online world, one can buy a bus ticket, bevarages from ATM, pay parking ticket, order a store catalog or some goods (e.g. discount movie DVDs) and many more. Premium-rated messages are also used in Donors Message Service to collect money for charities and foundations. DMS was first launched at April 1, 2004 and is very popular in the Czech Republic, e.g. the Czech people sent over 1.5 million messages to help South Asia recover from 2004 Indian Ocean Earthquake. The Value-added service provider (VASP) providing the content submits the message to the mobile operator's SMSC(s) using a TCP/IP protocol such as the short message peer-to-peer protocol (SMPP) or the External Machine Interface (EMI). The SMSC delivers the text using the normal Mobile Terminated delivery procedure. The subscribers are charged extra for receiving this premium content; the revenue is typically divided between the mobile network operator and the VASP either through revenue share or a fixed transport fee. Submission to the SMSC is usually handled by a third party. Mobile-originated short messages may also be used in a premium-rated manner for services such as televoting. In this case, the VASP providing the service obtains a short code from the telephone network operator, and subscribers send texts to that number. The payouts to the carriers vary by carrier; percentages paid are greatest on the lowest-priced premium SMS services. Most information providers should expect to pay about 45% of the cost of the premium SMS up front to the carrier. The submission of the text to the SMSC is identical to a standard MO Short Message submission, but once the text is at the SMSC, the Service Center (SC) identifies the Short Code as a premium service. The SC will then direct the content of the text message to the VASP, typically using an IP protocol such as SMPP or EMI. Subscribers are charged a premium for the sending of such messages, with the revenue typically shared between the network operator and the VASP. Short codes only work within one country, they are not international. An alternative to inbound SMS is based on long numbers (international number format, e.g. +44 762 480 5000), which can be used in place of short codes for SMS reception in several applications, such as TV voting, product promotions and campaigns. Long numbers work internationally, allow businesses to use their own numbers, rather than short codes which are usually shared across a lot of brands. Additionally, long numbers are non-premium inbound numbers. The GSM industry has identified a number of potential fraud attacks on mobile operators that can be delivered via abuse of SMS messaging services. The most serious of threats is SMS Spoofing. SMS Spoofing occurs when a fraudster manipulates address information in order to impersonate a user that has roamed onto a foreign network and is submitting messages to the home network. Frequently, these messages are addressed to destinations outside the home network – with the home SMSC essentially being “hijacked” to send messages into other networks. The only sure way of detecting and blocking spoofed messages is to screen incoming mobile-originated messages to verify that the sender is a valid subscriber and that the message is coming from a valid and correct location. This can be implemented by adding an intelligent routing function to the network that can query originating subscriber details from the HLR before the message is submitted for delivery. This kind of intelligent routing function is beyond the capabilities of legacy messaging infrastructure. Silent messages, often called "silent sms, "stealth sms," or "stealthy ping," will not show up on the display, neither is there an acoustical signal when they are received. However, at the mobile provider some data is created (for example, the subscriber identification IMSI). This kind of message is sent especially by the police to locate a person or to create a complete movement profile of a person. In Germany in the year 2010, nearly half a million "silent SMSs" were sent by the federal police, the customs, and the secret service "Office for Protection of the Constitution.
